What is Jointing?
Jointing is the point in the wheat's life cycle when the growing point moves above the soil surface.
At this point, the stem is beginning elongation and the tiny wheat head in the main stem and
each tiller is moving up the stem.
Why is it important?
This is a very busy time for a wheat plant. As the head begins to move up the stem, the maximum
possible of kernels per head is determined at this time. The plant allocates nutrients to the main
stem and tillers with at least three leaves. Once the plant has jointed, typically no more potential
head-bearing tillers will form.
However, if the growing point has been killed during stem elongation, as a result of damage
(physical, freeze, pests) to the immature head and supporting system, the main stem or tiller
will die. As a result, the wheat plant will tend to compensate for the loss by development of
new shoots from the base of the plant.
